Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune syndrome of central nervous system.The main clinical manifestations include psychiatric symptoms,movement disorders and seizures.It is often misdiagnosed as viral encephalitis.Tumors,especially the ovarian teratoma,play an important role in the disease.The prevalence in children is beyond imagination.Anti-NMDAR antibodies are specific diagnostic tests.Immune suppression is the main treatment.The first-line treatments include corticosteroids,intravenous immunoglobulin,and plasmapheresis.The second-line treatments include biological agents and cytotoxic drugs.Early diagnosis and treatment are essential for neurologic recovery.Overall prognosis is good.

Objective To investigate the effect of Tongxinluo capsule combined with metoprolol on elderly patients with coronary heart disease and angina pectoris and its influence on hemorheology and inflammatory factors.Methods 135 elderly patients with angina pectoris of coronary heart disease were selected,and they were randomly divided into treatment group (68 cases) and control group (67 cases).The treatment group was treated with Tongxinluo capsule combined with metoprolol,while the control group was treated with metoprolol.The two groups were treated for 8 weeks.The curative effect of the two groups was compared,the number and duration of angina pectoris,the changes of hemorheology and inflammatory factors before and after treatment were compared.Results The total effective rate of the treatment group (94.12％) was higher than 76.12％ of the control group (P ＜ 0.05).After treatment,the frequency and duration of angina pectoris in the treatment group were (6.03 ± 1.21) times/week and (3.02 ± 0.76) min/time,respectively,which were significantly lower than those in the control group [(9.87 ± 1.46) times/week and (4.86 ± 0.98) min/time] (t =16.649,12.201,all P ＜ 0.05).After treatment,the whole blood viscosity at high shear rate [(3.76 ± 0.41) mPa/s],whole blood viscosity in low shear [(8.13 ± 0.76) mPa/s],plasma viscosity [(1.23 ± 0.08) mPa/s],erythrocyte aggregation index [(2.06 ± 0.27)],fibrinogen [(2.46 ± 0.41) g/L] in the treatment group were lower than those in the control group[(4.53 ± 0.52) mPa/s,(9.61 ± 0.89) mPa/s,(2.09 ± 0.27) mPa/s,(2.63 ± 0.35),(3.53 ± 0.62) g/L] (t =9.562,10.396,25.170,10.604,11.844,all P ＜ 0.05).After treatment,the interleukin-6 (IL-6) [(8.49 ± 1.76) pg/mL],intercellular adhesion molecule-1 (ICAM-1)[(85.25 ± 8.92) pg/mL],C reactive protein (CRP) [(8.74 ± 1.76) mg/L] in the treatment group were lower than those in the control group[IL-6 (11.32 ± 2.10) pg/mL,ICAM-1 (103.42 ± 10.72) pg/mL,CRP (14.98 ± 2.24)mg/L] (t =8.491,10.712,18.012,all P＜0.05).Conclusion Tongxinluo capsule combined with metoprolol in the treatment of elderly patients with coronary heart disease angina pectoris has obvious curative effect,and can improve the patients'blood rheology and inflammatory reaction.

ObjectiveTo investigate the relationship between carotid atherosclerosis and progressing stroke.Methods103 patients with acute cerebral infarction within the first 24 hours from onset were tested with carotid color doppler ultrasonography during the first week from admission. Univariate and multiple logistic regression analyses were performed to examine the relationship between carotid intima media thickness (IMT), plaque structure, the degree of artery stenosis and the early deterioration of cerebral infarction.ResultsPrevalence of carotid plaque and thickness of IMT in patients with progressing stroke were higher than that in non progressing patients. In logistic regression, presence of carotid plaque was independent predictors of progressing stroke. Plaque size, extent of artery stenosis and IMT were not included in the regression model.ConclusionPlaque structure and its chemical feature may be the cause of progressing stroke.

Objective:To investigate the clinical characteristics and genetic mechanism of a patient with gout and hyperlipidemia.Methods:Clinical data of patient and his parents were collected in details, including their medical histories, physical examination results, and laboratory tests. DNA was extracted from the peripheral blood of the patient and their parents for whole exome sequencing. Protein function was predicted for new mutations.Results:The patient was a 22-year-old male with typical clinical manifestations of hypoglycemia, hyperuricemia, gout, and hyperlipidemia. c. 260delG(p.V88Ffs*13)frameshift mutation was detected in the second exon of the patient′s glucose-6-phosphatase(G6PC) gene, and c. 532C>G(p.P178A)missense mutation was detected in the fourth exon. The father and mother of the patient were heterozygotes carrying c. 260delG(p.V88Ffs*13)and c. 532C>G(p.P178A)mutations, respectively. Protein structure prediction showed that mutations were able to cause protein structure changes. The patient was diagnosed as glycogen storage disease type Ⅰa(GSD-Ⅰa)with secondary gout.Conclusions:The compound heterozygous mutation of G6PC gene is the pathogenic basis of this gout patient. The discovery of the new pathogenic mutation c. 260delG(p.V88Ffs*13)of the G6PC gene broadened the spectrum of pathogenic genes of GSD-Ⅰa and gout in Chinese patients.

With the development of society, eating disorders(EDs) have attracted people's attention because of their chronicity, high fatality rate and heavy social burden. However, the current treatment mainly includes psychotherapy and drug therapy, but the therapeutic effect is not satisfactory. Studies suggest that patients with EDs have brain abnormalities related to the prefrontal cortex. In recent years, the neuromodulation therapies, especially the non-invasive neuromodulation therapies, have become a research hotspot because of their few side effects and easy to use. At present, they have been used in mental disorders such as depression, obsessive-compulsive disorder, substance addiction and so on. A small number of studies on EDs have also been carried out. This paper reviews the related studies on anorexia nervosa and bulimia nervosa, and introduces the working principles of deep brain stimulation, transcranial magnetic stimulation and direct current stimulation and their efficacy in the treatment of EDs. Previous studies have shown that neuromodulation therapies are effective in the treatment of EDs. However, the existing research results are not exactly same, and the best parameters need to be clarified. In the future study, it is necessary to integrate cognitive, neuroimaging and biomarker data to identify different endophenotypes in EDs, so as to help clarify the disease mechanism, help patients with EDs to formulate individual treatment plans, improve clinical symptoms, and put forward suggestions and prospects for future research and application.

Coronal restoration of endodontically treated teeth may be viewed as one of the main parameters that influence the outcome of endodontic treatment. The purposes of restoring endodontically-treated teeth include preventing recontamination of the root canal system and periapical area, replacing the compromised dental hard tissue, restoring the coronal morphology and function, providing necessary strength for the restoration/tooth complex for functional stress, and avoiding crown and/or root fracture. This article reviewed recent researches on the restoration of endodontically treated teeth, provided evidence for clinical practice on topics as when to restore them, basic principles to be considered during treatment planning, and specific restoration options for both anterior and posterior teeth under different functional occulsal load conditions. Several issues should be taken into account during the decision making process, such as remaining tooth tissue, functional masticatory forces, comprehensive oral rehabilitation, and esthetic requirements.

As the most popular simplified model of the optical imaging system, the acquisition of the Gaussian point spread function (PSF) parameter is one of the hotspots and key points on which people do research in the field of image restoration. Based on the idea by which there exists deterministic mathematical relationship between Gaussian OTF feature points as well as its parameter and the frequency representation of the image in an existed literature, we proposed an automatic, accurate, stable, and improved approach. This method is able to give prominence to the related calculation feature by a Gaussian convolution and degeneration operation and finally realize the automatic esti mation of PSF parameter of a microscopic image. Experiments have proved that a good restoration result can be achieved utilizing the estimated PSF by the present method, which is of considerable application and reference value in restoration of other sorts with Gaussian approximate PSF model or 3D microscopic image restoration.

Objective To investigate the common critical value (CV) of patients hospitalized in the department of spine surgery and to determine the corresponding management. Methods Medical records of patients between 2013 January and 2014 December were retrospectively reviewed. 47 cases with CV were noted. The following characteristics of CV were recorded and analyzed, including time-point at occurrence, type, reason and management. Results Most of the CVs (43/47, 91.5%) were detected between 8 am to 12 am, and between 17 pm and 21 pm. Overall, there were 24 cases of abnormal blood electrolyte (51.1%), 13 cases of abnormal routine blood test (27.7%), 5 cases of abnormal blood coagulation test (10.6%), and 1 case of abnormal TnT (2.1%). The remaining 4 cases including 2 cases detected in the night (1 case of abnormal blood gas test and 1 case of abnormal TnT) and 2 cases detected in the afternoon (1 case of positive blood bacteria culture and 1 case of low blood glucose level). Conclusions The most common CVs were summarized in the clinical practice. The findings have important clinical implications concerning the management of these CVs. In addition, preventive modality of daily nursing and standardization of medical management should be applied so as to ensure the safety of patients and rapid recovery.

Objective To evaluate the validity and surgical outcome of emergency one-stage intestinal resection and tension-free hernioplasty for acutely strangulated inguinal hernia complicated with intestinal necrosis.Methods Clinical data of 58 patients diagnosed strangulated inguinal hernia and intestinal necrosis in our hospital from July 2011 to April 2014 were retrospectively analyzed.Of the 58 patients,33 were males and 25 were females,mean age of (64 ± 18) years (range 52-86).There were 28 strangulated inguinal and 30 femoral hernias undergoing emergency small bowel resection and tension-free mesh hernioplasty.Patients with intestinal perforations,preoperative peritonitis,inflammatory hernia and those who required colon resections were excluded from the study.Results The mean operative time was (92 ± 22) min (range,80-120 min).Average length of hospital stay was (8.6 ± 2.5) d (range,6-21 d).There were three postoperative c omplications (5.2％):one of subcutaneous hematoma,one of superficial surgical site infection and one of scrotal fluid collection,which were all cured by wound dressing,removal of infected prosthetic mesh,vacuum sealing drainage (VSD) and continuous irrigation,intravenous antibiotics and scrotal puncture.During a follow-up period of 6 to 32 months (mean 12 ± 6 months),there was no hernia recurrence.Conclusions Emergency one-stage intestinal resection and tension-free mesh hernioplasty for strangulated inguinal hernia complicated by intestinal necrosis is safe,feasible with a favourable outcome and low rate of postoperative complications.
